Searching in Chrome

I use Toodledo with Firefox as my browser. When I enter a term in the quick search window, the list quickly shrinks to only those items which meet the search criteria. When I do the same thing in Chrome, here is what happens:
1. The first search I do is EXTREMELY SLOW.
2. From there on, the searches are as quick as on Firefox...unless I refresh the screen.
3. When I refresh the screen, the next search is extremely slow again.

can anyone tell me what is happening with the quick searches in Chrome?
